Why Are Your Calla Lily Leaves Turning Yellow?

If you have been growing Calla lilies for a while, you may have noticed yellowing on the leaves of your plants. This can be frustrating, especially if you don't know what's causing it. Fortunately, there are several reasons why this could be happening, and many of them are easy to correct.

Overwatering

One of the most common reasons why Calla lily leaves turn yellow is overwatering. Although these plants require a lot of water, they can easily become waterlogged if you give them too much. When this happens, the roots can't absorb the nutrients they need, and the leaves will to yellow.

To avoid this issue, make sure you're not watering your Calla lilies too frequently. Allow the soil to dry out slightly before you water again, and be sure to plant your Callas in well-draining soil.

Underwatering

On the other hand, underwatering can also cause yellowing of Calla lily leaves. If your plants aren't getting enough water, they won't be able to absorb the nutrients they need to stay healthy.

To prevent this from happening, make sure you're watering your Callas regularly. Check the soil frequently to see if it's dry, and water as needed. You may also want to consider using a moisture meter to help you determine when it's time to water.

Nutrient Deficiencies

Yellowing of Calla lily leaves can also be caused by nutrient deficiencies. If your plants aren't getting enough of the nutrients they need, they won't be able to produce healthy foliage.

Some of the most important nutrients for Calla lilies include nitrogen, phosphorus, and potassium. If you suspect that your plants are lacking these nutrients, you may want to consider using a fertilizer that's specifically formulated for Calla lilies.

Pests and Diseases

Finally, yellowing of Calla lily leaves can also be caused by pests and diseases. Common pests that can affect these plants include spider mites, thrips, and aphids. If you notice any signs of pest damage, such as webbing or holes in the leaves, you should take steps to control the infestation immediately.

Diseases that can affect Calla lilies include fungal infections like root rot and leaf spot. To prevent these issues, make sure you're planting your Callas in well-draining soil, and avoid overwatering.

In conclusion, there are many reasons why Calla lily leaves may turn yellow. Overwatering, underwatering, nutrient deficiencies, pests, and diseases can all cause this issue. Fortunately, most of these problems are easy to correct once you identify the cause.

If you're having trouble with yellowing Calla lily leaves, take a closer look at your watering habits, soil quality, and plant health. With a little bit of attention and care, you can keep your Callas looking healthy and beautiful for years to come.
